Site Design

Minimum Measures for Site Design are:

• Clear zone - eliminate potential hiding places to improve site visibility
• Maximize standoff from the outer perimeter and parking areas
• Eliminate roadways or drives that approach perpendicular to a building
• Minimize the number of access points to the facility
• Avoid parking under a facility
• Provide adequate security lighting
• Reduce or avoid vantage points
